本文實例講述了Java基於IO流讀取檔案的方法。分享給大家供大家參考,具體如下:
public static void readFile(){ String pathString = TEST.class.getResource("/simu").getFile(); try { pathString = URLDecoder.decode(pathString, "utf-8"); } catch (UnsupportedEncodingException e1) { e1.printStackTrace(); } System.out.println(pathString); File file = new File(pathString,"test.txt"); InputStream is = null; try { is = new FileInputStream(file); } catch (Exception e) { e.printStackTrace(); } BufferedReader br = new BufferedReader(new InputStreamReader(is)); StringBuffer sb = new StringBuffer(""); String b = ""; try { while((b=br.readLine())!=null){ sb.append(b).append("\n"); } } catch (Exception e) { e.printStackTrace(); } String bb = sb.toString(); System.out.println(bb); }
希望本文所述對大家Java程式設計有所幫助。
